Hi Christopher,

For arch maintainers there are some simple tests to be able to quickly
verify that the syscalls are working correctly here:

I'm wiring up these new syscalls on m68k.

http://ozlabs.org/~cyeoh/cma/cma-test-20110718.tgz

The included README talks about:

    setup_process_readv_simple
    setup_process_readv_iovec
   setup_process_writev

while the actual test executables are called:

    setup_process_vm_readv_simple
    setup_process_vm_readv_iovec
    setup_process_vm_writev

On m68k (ARAnyM), the first and third test succeed. The second one
fails, though:

# Setting up target with num iovecs 10, test buffer size 100000
Target process is setup
Run the following to test:
./t_process_vm_readv_iovec 1574 10 0x800030b0 89 0x80003110 38302
0x8000c6b8 22423 0x80011e58 18864 0x80016810 583 0x80016a60 8054
0x800189e0 3417 0x80019740 368 0x800198b8 897 0x80019c40 7003

and in the other window:

# ./t_process_vm_readv_iovec 1574 10 0x800030b0 89 0x80003110 38302
0x8000c6b8 22423 0x80011e58 18864 0x80016810 583 0x80016a60 8054

copy_from_process failed: Invalid argument

Any suggestions?
